23. Apr. 2014 · In the standard ΛCDM model of the Big Bang, the universe is infinite and has always been such. The Big Bang singularity happened everywhere, in the sense that far back enough in time, the density diverges to infinity at every place. But this is just a particular model--it assumes that the universe if spatially flat and is globally homogeneous ...
12. Nov. 2016 · The measure in the middle of the image represents 1.5 billion light years. light travels in every direction, and at the time of the big bang, there was no light to travel anywhere, and early in the theory of the big bang, there were no 3D directions that we can conceive, no definition of straightness and edge, no distance in between anything in ...
21. Feb. 2016 · But after the universe had cooled (it took sometime between 10 − 36 and 10 − 32 seconds) the weak and electromagnetic fields split, and the first true photons formed. These photons didn't get very far before colliding with other particles that were being formed. As you note, it took nearly 400000 years until the universe cooled enough to ...
19. Okt. 2015 · As relativistic effects will cause clocks to run slower, a frame of reference must be chosen when considering the time of the "big bang". There is a natural and convenient choice of reference frame, based on the cosmic microwave background. The cosmic background appears to be extremely red-shifted light, indicating it is receding from us very fast, due to the expansion of the universe. If we ...
19. Dez. 2016 · There are two explanations for the quantization that do not require exotic cosmologies. The first is the large scale clustering of galaxies that traces the cosmic web. The walls and filaments formed in this web leads to groupings of galaxies around specific redshifts along the line of sight. The second explanation is the quantisation of ...
Following the Big Bang the Universe continues to expand, presumably and roughly equally in all directions. It is understood that the Big Bang occurred 13.798 ± 0.037 billion years ago. Is there any way for us to know how far we are away from the nearest edge of the expansion front of the Big Bang? universe. big-bang-theory.
7. Jan. 2016 · The Universe is, and has always been, infinite. The Big Bang was just when the Universe's expansion really began — that is, when objects started drifting away from each other. The Universe was still infinite, but there was less space between the matter. This density caused the Universe to get extremely hot and expand.
If you ranked all the explosions in the universe based on their power, gamma-ray bursts would be right behind the Big Bang". I'm asking this question in the tentative to compare the Big Bang to a gamma-ray burst. I keep in mind that a key difference between both is that Big Bang was Not an explosion, but want to know similarities to point out.
2. The most significant assumption is that very shortly after the Big Bang, the universe expanded very rapidly for a short period of time. Much faster than normal expansion due to Big Bang. It was an exponential expansion and occurred around 10−32 10 − 32 seconds after Big Bang and lasted for tiny fraction of second.
1. The solar system and the Earth have formed billions of years ago from a pile of stuff (mostly hydrogen gas and rocks, with traces of other things) that collapsed together due to gravity pulling all those parts together. The current orbital speeds and spin motions of planets are just residuals from that collapse.
